A) 64 q, C
B) 16q, 4C
C) 64q, 4C
D) 16q, 64C
Correct Answer: C
Solution :
64 drops have formed a single drop of radius R. Volume of large sphere \[=64\,\times \]Volume of small sphere \[\therefore \,\,\,\frac{4}{3}\pi {{R}^{3}}=64\frac{4}{3}\pi {{r}^{3}}\] \[\Rightarrow \,\,\,\,R=4r\] and \[{{Q}_{total}}=64q\] \[C'=4\pi {{\varepsilon }_{0}}R\Rightarrow C'=\left( 4\pi {{\varepsilon }_{0}} \right).\,4r\Rightarrow C'=4C\]
